Bug fix: Free all memory and give better messages when memory is full.

* plugin-runner.c (add_to_char_array): Bug fix: If realloc fails, do
                                       not change old array pointer.
  (add_environment): Bug fix: If realloc fails, do not change old
                     environment pointer.  Also rename "e" to "envdef"
                     for clarity.
  (main): Bug fix: If realloc fails, do not change old pointers.  Also
          wrap "#pragma GCC" with "#ifdef ___GNUC___".
* plugins.d/mandos-client.c (incbuffer): Bug fix: if realloc fails,
                                         free old buffer.
  (run_network_hooks): Moved variables "directory" and "ret" to their
                       innermost possible scope.
  (take_down_interface): Moved variables "sd", "ret_errno", and
                         "ret_setflags" to their innermost possible
                         scope.
  (main): Removed variable "interfaces_hooks_size".  Also, if argz_add
          fails when adding all found interfaces, the error message
          will now be correct.  Also print error message if, after
          having taken up an interface, argz_add fails to add
          interface to list of interfaces to be taken down.
* plugins.d/mandos-client.xml (OPTIONS): Explain better what "none"
                                         means as argument to
                                         "--interface" by negating
                                         sense.
* plugins.d/password-prompt.c (fprintf_plus): Removed (unused).
